Please ignore my comment.
I will try to use exported tegra_fuse_readl().

Could we move this fuse.h to other folder under /include/linux (like 
/include/linux/platform_data) for other driver to include?

I don't think we should expose everything in fuse.h to the world.

So other driver can invoke function to read fuse data if needed.

Which functionality do you want? Just reading the fuse data exposed in the sysfs file from a driver? exporting tegra_fuse_readl() should do that I think?

Cheers,

Peter.
